Hi there, I am new to this forum so heres my little hello. I do have a question for all you cavy lovers, I currently have a 2x5 bottom cage with fleece bedding, and a 2x2 top with care fresh and their hay. The top part is no problem for me mess wise. The issue I have is I first had one guinea pig that was 100% litter trained to only wee upstairs, then two weeks ago i got a second guinea pig and he just wont figure out the system punzy and I have going, I have a litter box in the bottom corner and have been placing some of his poops in there but he wont take. The smell is so bad I am changing the fleece bedding more than twice a week versus every ten days or so from before. My parents can't stand the smell and complain constantly, I just can't keep up with it. Does anyone have any advice to get him to wee upstairs? I feel like I'm running out of options.
